BRO ODER.

Specification of Letters Patent.

Patented June 16, 1914.

AppIication led August 19, 1912. Serial No. 715,791.

To all whom it may concern.'

Be it known that I, HARMON A. GEORGE, a citizen of the United States, residing at Petaluma, in the county of Sonoma and State of California, have invented new and useful Improvements in Broeders, of which the following is a specification.

This invention relates to `a broeder.

1t. is the object of this invention to provide a broeder for young chickens and other fowls in which the heating feature is obtained by the introduction of warmed pure air, and notl by direct radiation.

Another object is to provide a broeder having two compartments, one of which is heated to a greater temperature than the other, so that chilled chicks may be quickly warmed in the latter and afterward pass to the cooler compartment.

Another object. is to so construct the heating elements of the broeder that the products of combustion will not be delivered thereto and mixed with the warmed fresh air, and to provide means for Ventilating the broeder to insure a continuous circulation of incoming fresh air and outgoing foul air.

A further object is to provide a broeder which is sanitary and readily cleaned` simple and inexpensive in construction, efficient in operation, and which is effective in utilizing all the heat generated, thereby rendering it conducive to an economical use of fuel.

The invention primarily resides in forming a broeder with a top spaced from the floor and from which depend two rows of curtains to divide the space beneath the top in two compartments, delivering warm fresh air to the inner compartment through a passage having a heating coil or flue therein, and introducing a heating element into the coil.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a view in Vertical section of the invention. Fig. 2 is a plan View of saire with parts broken away.

In the drawings A represents the side walls of a broeder house of any suitable construction having the usual floor B. Disposed at any convenient point in the house A is a broeder-box, consisting of a top 2 supported on legs 3 and having a continue-us peripheral vertical side strip 4, the lower edge of which is spaced from the floor B to allow the ingress and egress of the chicks thereunder. The strip 4 has ventilating perforations 4 around the box beneath the top D for the purpose hereinafter stated. A

vcurtain 5 depends from the lower edge of the strip 4, and a circular curtain 6 depends from the underside of the top 2 about midway between the outer edge and its center.

The curtains 5 and 6 are of any suitable soft fabric and extend to a point adjacent the floor B, and divide t-he space in the breeder-box into two broeder compartments, indicated at C and D, respectively, in Fig. 1, and which compartments are designed in practice to be kept at diiferent temperatures.

Disposed beneath the Hoor B is a fresh air supply pipe or conduit 7, which opens at its inner end to the central or inner compartment C through the Hoor B, and has its outer end terminating outside of the walls A of the broeder house., which outer end is normally closed by a hinged door or gate 8 of any suitable description. Opening to the conduit 7 near its outer end is a downwardly extending hood 9, through which fresh air is admitted to the conduit 7, and placed within the hood 9 and spaced therefrom, is a second hood 10, the lower end of which extends below the lower end of the outer hood 9 and surrounds a burner 11, of any suitable construction. The upper end of the inner hood 10 connects with and opens to a pipe 12 extending into the conduit 7 and terminating in a T-joint 13. Leading from the T-joint 13 is a horizontal pipe 14 which extends approximately the length of the conduit 7 and returns to a point adjacent the outer end thereof, where'it terminates in a T-joint 15, from which an upwardly extending pipe 16 leads outside of the walls A of the broeder house. The inner hood 10, pipes 12, 14, and 16, form a flue for the hot gases generated by the burner 11, which, on passing through the pipe 14 heat` the latter so as to raise the temperature of the in the pipe 7 by radiation. The outer ends of the T-joints 13-15 are closed by means of plugs 17, which are removed when it is desired to clean the pipe 14; the door 8 being provided as a means of access thereto.

The inner end of the pipe 7, where it extends through the floor B, is designed to connect with a detachable extension or joint of pipe 18, which projects upward and terminates a short distance below the top 2 and opens to the inner compartment C. The pipe 18 is removed and the open inner end of the pipe 7 is closed by a suitable cap when it is desired to remove the broeder and after the chicks have attained such size as not to require it.

Formed in the top 2, immediately over the open upper end of the pipe 18, is an opening 19 which is normally closed by means of a cap 20. Then it is desired to heat the broeder house direct, or reduce the temperature of the brooder-box, the cap 20 is removed so that the hot air emitting` from the pipe 18 will be discharged into the broeder house through the opening 19.

In the operation of the invention, the hot gases generated by the burner 11 pass upward through the hood 10 and pipe 12, thence through the pipe 14 and are discharged from the pipe 1G outside of the broeder house. The hot gases act to heat the pipe 14 which will then perform the function of a heating coil and heat the air surrounding it in the conduit 7. It is manifest that any number of pipes 14 may be disposed in the conduit 7 as may be desired.

The air in the conduit becoming heated, rises and passes out of the pipe 18 into the inner compartment C, thence under and through the curtain 6 into the outer compartment D from whence it passes into the broeder house beneath and between the eurtains 8; fresh air entering the conduit 7 through the hood 9 as the heated air passes therefrom. From this it will be seen that a constant supply of heated fresh air will be delivered to the broeder, the incoming fresh air crowding out the impure air breathed by the chicks, through the perforations 4 formed in the side strips 4 adjacent the underside of the top 2.

It is obvious that the inner compartment C will be heated to a greater extent than the outer compartment D, by reason of the heated air being delivered direct thereto and confined therein a short time before passing to the outer compartment. By this arrange` ment such chicks as may be chilled can be quickly warmed by passing into the inner compartment C. They can then return to the cooler outer compartment D, when sulficiently warmed.

rl`he heating ofthe broeder by the intro-- duction of warm air therein at a point adjacent the top thereof, deflects the warm air downward from above the chicks, thereby precluding any possibility of the chicks heing burned, as might be the case where direct radiation is employed.

The pipes 14 and conduit 7 are of such length that the heat generated by the burner 11 will be fully utilized in heating the air in the conduit 7. The temperature of the heated air can be regulated by adjustingthe flame of the burner 11 in any desired manner as required.

Among the advantages of this broeder are that no products of combustion are allowed to enter into the broeder; the conduit 7 is of such length and diameter that a sullicient quantity of fresh air is always in contact with a considerable area of the heated pipe 14; the division of the broeder-box into two compartments allo-ws the more delicate chicks to get closer to the source of heat by passing under the curtain G to the inner compartment C; any chicks that find it too warm in compartment C and move out into compartment D can still. be housed and protected by the mothering influence of the broeder box; the perforations 4 in the continuous strip 4 provide for perfect ventila tion; the broeder house is quickly heated at any time and the heat diverted from the broeder house by simply removing the cap Q0.

Having thus described my inventiomwhat I claim and desire to secure by Letters Patent. is

The combination with a broeder, of a hover-box having a top provided with a cen trally located opening, a relatively still depending perforated strip adjacent its margin, a flexible curtain attached to the outer face of said strip below the perforations, a` second shorter curtain attached to the top of the boX in a position between the outer curtain and the central opening entirely within spaced from and substantially concentric to said outer curtain, a removable cap normally closing the opening in the top of the inner compartment of the hover, an inlet pipe having its discharge end adjacent said opening, and an air heating system snpplying the inlet with pure warmed air and discharging all products of combustion outside of said broeder.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

I-IARMON A. GEORGE.
